those with hot start issues.. without touching the software settings
.. please try sitting patiently for about 40 secs just jogging the key to on every time the pump stops
.. just seeing if you have perculation issues that will be resolved by cycling cooler fuel through the rails
( and by playing the post start enrichment for high engine temps )

thanks for fast answer
I have fuel pumps separate switch and the fuel tank is 10gallons. All the time is circulation between fuel rails and fuel tank. It took me 15-20min to cool the engine and then it starts, probably with the same fuel temp.

Do you actually have spark while cranking? Voltage drops to 10v while cranking.
I don`t know
hot/cold engine the same voltage drop but I never check it when it`s hot.
And your split timing map is all wrong.
yes I know, I`m working/testing too high EGT at idle
at the moment the battery is charging, I must check this spark immediately

it will be helpful
ps1000, ported 13b-rew from fd3s with ls1 coils, full Block Off Plate Kit, no idle cotrol, no OMP etc., single turbo, 550+1450cc, stock trigger, ATC CTS sensors by haltech
today we have pretty good weather, no raining so I can drive and check spark while cranking when it`s hot

- Are you using the FFE trigger kit? Trigger angle with those is supposed to be 90*.
- Did you wire the trigger loom with the green wires for ground? If so, and you should have, the check boxes for -ve at the bottom of the page should be unchecked.
- No way you should need that much trigger filter. Are you even getting an RPM signal when you're cranking it and it won't start?
- Why is the filter level of the TPS set to 20?
I don't see anything in the mapping that would keep it from starting. I'd change some stuff, but it should fire. The trigger settings are all wrong and if the trigger angle is wrong, you're timing is 10* retarded.

This 100% fixed my hot start issues. thanks ludwig.
